In the form shown,this means comprises a piston 14 mounted for reciprocation within thecylinder 5 and provided at its outer end with a head 15 having threadedconnection with the piston as at 16. A discharge passage 1'7 formedwithin the piston is adapted to communicate at its inner end with thecylinder 5, and at its outer end opens into the chamber 18 formed in thehead 15, the chamber 18 in turn communicating with a plurality of spacedoutwardly extending delivery nozzles 19. These nozzles preferably arethin, i. e. of small diameter and somewhat elongated so as .toY becapable of penetrating and extending deeply into the bristles of a brushto which shaving cream is to be delivered. 1 A ball valve 2O urged toclosed position by means of a spring 21 interposed between the ballvalve and the outer end of the head 15 controls communication of thecylinder with the discharge passage 17 and a spring 22 surrounding thepiston and being disposed between the body 1 and the head 15 urges thepiston and head outwardly with respect to the cylinder 5. A strip 23secured to the lower side `of the head by means of a screw 24 is formedwith an upturned end 25 mov#- able in a slot 26 in the bottom of thebody 1 and engageable with the end 27 of the slot for limiting outwardmovement of the piston and the head.

In operation, assuming the piston 14 and head 15 to be in the positionshown in Figure 2, the inlet opening 6 and cylinder 5 willbe lled 'withshaving cream. To deliver cream through the nozzles 19, the head andpiston are moved tov theleft.. As soon as the inner end of the pistonpasses the inner side of the inlet opening 6 so as to cut off the latterfrom communication with the cylinder, the` ball valve 20will be forcedopen and shaving cream will be delivered through the passage 17, thechamber 18, and the nozzles 19.

In order to conceal the operating `parts just described and to preventthe accumulation of dust thereon, I preferably provide Va casing y28open at its outer or right hand endand being mounted on the body 1 insurrounding relation to the operating parts. As shown, the casing isprovided at its upper side with a clip 29 adapted to engage a notch 30on the upper side yof the body 1. The lower wall of the casingisarranged to, i'ltunder a bottom ange 31 onV the body l. The flange 31is formed on its inner and upper face with a latch nose 32 which isengageable by a springvlatch 33 secured to the inner face of the casingk28. Preferably the latch is provided with abutton 34 extending throughan Vopening Y35 in the bottom wall of the casing to facilitatedisengagement of the latch from the nosel so as to permit removalof thecasing when it is desired to adjust the operating parts in a manner tobe described. K k

In accordance with a further feature of the invention, means areprovided .for engagement with Si the body ofv a brush whose bristles aredisposed to encompass the ends of the nozzles 19 for actuation by thrustexerted by thebrush body for expelling cream and delivering it into theinte` rior of the bristles. In the formeshown, this means comprisesanoperating member 36 formed to ,include a housing 3'7 the inner end "ofwhich is fitted over the head 15, an 'outwardly ared outer end part 38,and an 'apron 39 surrounding thehousing 3'7 and being slidable within avguide formed by an inwardly folded ang'e 40 on the open end of thecasing 28. As shown in Figure 3, the housing 3'? is provided on one sidewith a slot 41 through which extends a locking screw 42 having threadedengagement with the head 15. For purposes to be set forth later, thehousing is adjustable with respect to the head 15 in the direction ofmovement of the latter, and the screw 42 serves to lock the housing inthe desired adjusted position. v Y

In operation, assuming that the parts are in the positions shown inFigure 2, with the exception that the reservoir 3 is empty and thefollower 11 is at the bottom of the reservoir, in order to render theapparatus ready for use, one or the other of the closure plugs 9 or 1Gis removed, dependingupon the size of the thread on the nozzle of thetube from which the cream is to be supplied to the container. The supplytube is then screwed into the opening 7 or 8, as the case may be, andthe cream forced into the containerby collapsing the tube' in' the usualmanner. v Material Ientering the container will contact with the bottomside of the follower and will movethe latter upward'- ly. Thereafter airwill'not contact with the niaterial, and oxidation ofthe latter will bepr vented. Y y, l l e When it is desired to deliver shavingcream'to theinterior of the bristles of the shaving brush such as the brush Bindicated in dotted lines in Figure 2, the bristles B .of the brush areinserted into the housing 37 and the brush moved irij'-I wardly untilthe body portionB thereof engages the flared end 38 of the member 36.The brush B shown in Figurev2 has relatively long bristles, and, inorder to prevent the ends of the latter from being forced intoengagement with the head 15, the housing 37 is so adjusted withrespeetto the head 15 that thefiared end 38 is disposed relatively farfrom the head. `This adjustment, is effected by loosening the screw 42and sliding thel housing outwardly with respect to the head l5, afterwhich the screw 42 is tightened so as to maintain the housing in thedesired adjusted posil tion. Y With the brush in the position shown-inFigure 2, the nozzles 19 extend into the bristles B. To deliver shavingcream to the interior of the bristles, the brush is moved to therleft,so that the body part B exerts a thrust upon the flared outer endportion 48, thus moving the head 15 and piston 14 to the left. Aspreviously stated, such movementof the piston will cause cream to bedelivered through the passage 17 an-d the nozzles 19 into the bristles.Whenthe desirefd amount of cream has been delivered, the brush B iswithdrawn, permitting the parts to assume their iigure 2`positions,after which the'A brush maybe wet and the lather produced in the usualmanner. v

When the apparatus is employedl for delivering shaving cream to a brushhaving relatively 'short bristles, such for instance as the brush Cshown'in Fig. 3, the locking screw 42 is loosened and the housing 37 isadjusted inwardly with respect to the head 15 so as to bring the housingand head to the relative positions shown in Figure 3, after which thelocking screw 42 will be tightened `to maintain the parts in the newadjusted position. With the parts in the new position, the body part C"of the brush C will engage the flared end 38 of the housing while thebristles C encompass the delivery nozzles 19 without contacting with thehead 15. The housing 37 serves not only to transmit thrust from thebrush body to the head 15 and the piston 14, but serves'also to confinethe brush bristles and to hold them together around iso rio

the discharge nozzles so as to prevent material emerging from thenozzles from being forced through the brush bristles.

' In accordance with the modification shown in Figure 5, thev filleropenings ,'7 and 8 are omitted and a detachable reservoir 43 is used inplace of the permanently mounted reservoir 3 shown in Figures l, 2, and4. The reservoir 43 is provided with an internally threaded bottomopening 44 adapted to receive an externally threaded iitting 45 on theupper end of the body 1, this tting forming a continuation of the inletopening 6 in the body. The detachable reservoir 43 may be removed whenempty and replaced with another and like reservoir, thus doing away withthe necessity of forcing cream into the container from the usualcollapsible tube.

Although the illustrative forms of apparatus shown and described hereinare considered to be preferred embodiments of the invention, it will beunderstood that various changes may be made in the specific constructionand arrangement of the parts without departing from the scope of theinvention as defined in the claims. 25
